executing the example ranking code I get the following error. It seems to me a parameter is used that is not supported by xgboost.

Hello,

The parameter "eval_set" in the function XGBRanker.fit is not passed to the xgboost train function.

win7 py2.7 xgboost 0.7
when run xgbranker_example, I get error as this


I add 'n_jobs' and 'random_state' to class XGBRanker.init(), This error dispeared, but I get a new error as this

When I set seed=0 in class XGBRanker.init() and run xgbranker_example again, get a new error as this:

I have no idea about this error!

Currently the API of the XGBRanker is not in line with the scikit-learn api. The predict method needs to have the groups keyword as an input, something with does not adhere to the sklearn standards.

I would like to propose to make the groups indiciator part of the dataset being fed into the fit and predict methods, e.g. as the first column. As a result of this we would be able to use sklearn to do cross validation for example (something which is currently not supported by the XGBoost module itself: dmlc/xgboost#270). If you like this idea as well, I would be happy to open a PR for this.

Conventional, the order of predict values should be consistent with the input, so I think the predict and apply int XGBRanker may has error.

The fit function leads to a parameter error, maybe this has to do with different version of xgboost

When installing using setuptools the subpackages are not included because setup.py only explicitly mentions the top level xgbextension package.

On the above line, should be {} instead of None, otherwise pickling (for parallel CV) will still not work.

Also note that this functionality is not present in the pip packages, I think the classes are not registered for packaging or smth.

Finally, I find the multiple classes quite too much, the same can be achieved with a single class in the style of:

class RankingScorer(_BaseScorer):
    def __init__(self, score_func, sign=1, k=None, stats=False):
        """
        Base class for applying scoring functions to ranking problems.
        This class transforms a ranking metric into a scoring function
        that can be applied to estimations that take a group indicator in
        their first column.
        
        Parameters
        ----------
        sign: maximize/minimize
        k: optional, if @k scorer
        stats: metric from scipy.stats, e.g. only use [0] element
        """
        super(RankingScorer, self).__init__(
            score_func,
            sign,
            {}
        )
        self.k = k
        self.stats = stats


    # First column of X has to be the group indicator
    def __call__(self, estimator, X, y, sample_weight=None):
        group_labels = X[:,0]
        (sizes, order_ixs) = group_col2len(group_labels)

        # reorder X and y (assumption of predictor)
        X = X[order_ixs, 1:]
        y = y[order_ixs]

        y_predicted = estimator.predict(X)
        return self.val(sizes, y, y_predicted)

   # also easy for non-sklearn access
    def val(self, sizes, y_true, y_pred):
        # indices at which to split
        split_indices = np.cumsum(sizes)[:-1]

        # Split into a different set for each query
        y_true_split = np.split(y_true, split_indices)
        y_pred_split = np.split(y_pred, split_indices)

        # Go through each query and calculate the statistic's value
        results = np.zeros(sizes.shape[0])
        for i, (yg_true, yg_pred) in enumerate(zip(y_true_split, y_pred_split)):
            r = None
            if self.k == None:
                r = self._score_func(yg_true, yg_pred)
            else:
                r = self._score_func(yg_true, yg_pred, self.k)

            if self.stats:
                r = r[0] # scipy.stats returns (val, significance)
            results[i] = r

        # Return the average over all statistics
        return self._sign * results.mean()

In sample xgbfeature_example.py, data's shape is 40×4, taget's shape is 40×1, why the index of leaf index for each tree is 40×50? I look forward to your reply. Thank you.

not important

Hi and thanks for this nice extension. I was wondering if in your examples folder you could also provide an example on ranking with order relevance. What I mean by that is the following. I have a dataset of the following format:

group_id, data_points[feature_vector1, feature_vector2, feature_vector3, .., N], position[position_of_feature_vector1: 0, position_of_feature_vector2: 1, positon_of_featrure_vector3: 4, .., N]

Eventually I want to predict all the feature_vectors belonging into a group_id while maintaining the order of them as it appears in the position matrix.

In the test set I would like for each group_id to predict N feature vectors in the order that they appear in the training data. Does that make sense?

Thanks!

mark,i am doing ranking task too.
